Hi,

 

I am trying to learn to build an OOT module using python.

 

To start with, a simple vector source (though it is already their) !, But I have further plans after the initial phase is complete.

 

Aim : The block should take in values from user for example (1,1,0,0) and output the same.

 

I am following the tutorial :  https://wiki.gnuradio.org/index.php/Guided_Tutorial_GNU_Radio_in_Python

 

After adding the block in gui & running it gives error (line 24, testing_source.py, I am attaching all the files that I created. Can you please help me, where I did wrong?
